Need a Script to change a specific color to another

Bonjour Peter,

Une idée...

// JavaScript Document
// meme_fillColor.js
var CO = [0,75,64,9];
var couleur = macmykColor(0,96,83,0);
var docRef = app.activeDocument;
var pathes = docRef.pathItems;
var titres = docRef.textFrames;

   compar(pathes,CO,0);
   compar(titres,CO,1);
// ----
function compar(tabs,CO,d) {
  var obj, color, cyan, magenta, yellow, black;
  for (var i = 0; i < tabs.length; i++) {
    obj = tabs[i];
        color = d ? obj.textRange.fillColor : obj.fillColor;
        if (color.typename == "SpotColor") {
          color = color.spot.color;
        }
        cyan    = Math.round(color.cyan);
        magenta = Math.round(color.magenta);
        yellow  = Math.round(color.yellow);
        black   = Math.round(color.black);
       if (cyan == CO[0] && magenta == CO[1] && yellow == CO[2] && black == CO[3])
          if (d) obj.textRange.fillColor = couleur;
          else obj.fillColor = couleur;
  }
}
// ----
function macmykColor(c,m,j,n)
 { //crée une nouvelle couleur CMJN
  var cmykColor = new CMYKColor();
    with (cmykColor) {
      cyan = c;
      magenta = m;
      yellow = j;
      black = n;
    }
  return cmykColor;
 }
// ----
